Mr. C's Word Problem Challenge #2 RESULTS

Thank you to all of you who took part in the 2nd word problem challenge. I need to apologize for the fact that I have been a little delayed with my updates. It has been a hectic couple of weeks and there is more to come. Therefore, I am going to allow TWO WEEKS for each problem. I will post the next challenge later this week, so please check back.

The correct answer to the word problem was 515 mg. You really needed to read the problem carefully to determine the amount of calories burned. Once you found the total for the three days, you then divided by 6 because I lost 1 mg for every 6 calories burned. Did anyone remember the divisibility rule for six? Just a refresher: If a number is divisible by 2 and has a digital root of 3,6, or 9, then it is divisible by 6. Here are the students who solved the problem correctly:

* Steven Mason
* Julia Moody
* Charlie Mahanes
* Richard Cummins

I have just written the names on individual slips of paper and dropped them in a plastic cup. I am going to close my eyes and draw out a name. The winner is . . .

STEVEN MASON!!!! Congrats Steven. Your prize will be mailed soon. Oh and Woodson Weathersby, I haven't forgotten about your prize. I am mailing it tomorrow. Sorry about the delay. Have a great day!!

Mr. Champion's Math Challenge #2 (June 22nd - June 29th)

Here is the problem for this week. Sorry it took me so long to post it. Just do your best to solve it and then email with me with the answer and an explanation of how you solved it. You may email me at championmathchallenge@yahoo.com. Good luck.

Problem: 
Mr. Champion went running three days in a row. The first day he burned 618 calories. The second day he burned half as much as the first day. On the third day he burned 7 times as many as the second day. If he loses a milligram (mg) for every 6 calories burned, how many milligrams did he lose in those three days?

Champion Word Problem Challenge #1 Update

Hello all,
      Thanks to those kids that took the time to try to answer last week's problem. The correct answer was 28 yard. First you multiplied the elapsed time between tides (6 hours) and multiplied it times 14 feet per hour and you would get a product of 84. Then to convert from feet to yards you would divide by 3 because there are 3 feet in a yard. 84 divided by 3 is going to work out evenly because the digital root of 84 is 3 which means that 84 is divisible by 3. 84 divided by 3 equals 28. Therefore the tide moved 28 yards. Here are the people who qualified for the drawing this week:

* Derrick
* Woodson
* Julia
* Neely
* Polly
* Jack

AND THE WINNER FOR THIS WEEK IS . . . WOODSON!! Congrats to Woodson. Your small prize will be coming your way in the mail soon. I will be posting a new problem tomorrow afternoon. Be sure to look out for it. Encourage your friends to take part as well. Have a great week! I miss you guys!

Here is the problem for this week. Just do your best to solve it and then email with me with the answer and an explanation of how you solved it. You may email me at championmathchallenge@yahoo.com. Good luck.

Problem: 
Mr. Champion went to the beach last week. On Tuesday, the morning low tide was at 3:30 AM and the morning high tide was at 9:30 AM. If the tide moved up at a rate of 14 feet per hour, how many yards did the tide move between low and high tide?

IMPORTANT IXL MESSAGE!!!!!!

I have slightly changed the requirement for IXL due to the holiday break. I am asking that the students complete 60 minutes of IXL work between now and Friday, February 24th. Please see the previous post to see what skills need to be covered. Also, the video that was shot today in 4E's class won't be able to be posted until tomorrow due to some technical issues. Have a great night!

IXL Skills for February 14th - 21st

Here are the skills you need to work on this week. Please be aware that your 45 minute requirement needs to be completed by Tuesday, February 21st. I believe that you should be able to master the below skills before you complete the 45 minutes. If that is the case, please ask me what other skills you might work on. Thanks and have a great day!

Skill #1: 4th Grade P.22 (lines, line segments, rays)
Skill #2: 4th grade P.10 (acute, right, obtuse, and straight angles)
Skill #3: 3rd grade R.6 (perimeter) - YOU SHOULD HAVE A PIECE OF PAPER HANDY :) - When your SmartScore gets into the 70s or 80s, you will have some word problems that are a bit difficult. We will talk about these in class.
Skill #4: 3rd grade R.7 (perimeter: find the missing length) - YOU SHOULD HAVE A PIECE OF PAPER HANDY :) - BEFORE you do this skill, watch the video on how to find missing length.

Helpful Rules for Comparing Fractions

Hello,
I mention these in the accompanying video, but I wanted to have them in print as well. So here goes:

LIKE NUMERATORS
To have like numerators means that two or more fractions have the same numerator (top number). When comparing fractions with like numbers, follow these steps:
1) Make sure the numerators are the same.
2) Look at the denominators (bottom numbers)
3) The fraction with the larger denominator is the SMALLER fraction. Again, the fraction with the larger denominator is the SMALLER fraction.

Example:
2/5 and 2/9
They both have 2 in the numerator. So I look at the denominators. 9 is the larger denominator, so 2/9 is the SMALLER fraction. Therefore, 2/5 is greater than 2/9.

LIKE DENOMINATORS
To have like denominators means that two or more fractions have the same denominator (bottom number). When comparing fractions with like denominators use these steps:
1) Make sure the denominators are the same.
2) Look at the numerators
3) The fraction with the smaller numerator is the SMALLER fraction.

Example:
3/8 and 5/8
They both have 8 in the denominator. So I look at the numerators. 3 is the smaller numerator, so 3/8 is the smaller fraction. Therefore, 3/8 is less than 5/8.
